Objective: Musical performance-associated musculoskeletal disorders are a common health problem among professional musicians. Awkward upper body posture while playing the instrument that causes unergonomic static strain on the back and unergonomic limp-movements. Our study aims to analyze static and dynamic postural risk factors and its relation with pain in students playing cello.
Materials and Methods: Nineteen conservatory students (18,05 ± 4,15) participated as volunteers. Static posture analysis was donefrom all directions. To identify postural problems during cello playing, the performance during a standardized gam work was videotaped. The record was taken from each direction. Then the videos were analyzed with the program for each musician's ROM were calculated for each joint separately. Pain intensity and pain regions of musicians were evaluated with visual analog scale and Mc Gill pain questionnaire. The angles were calculated and its correlation with pain was calculated with Pearson correlation coefficient. Increased lumbar lordosis, protrusion and depression of the shoulders, and anterior tilt of head was found in approximately sixty percent of the participants.
Results: During performance excessive or awkward movements were stated for neck flexion (44,94 ± 10,97), right wrist ulnar deviation (24,70±3,82), and radial deviation (17,86 ± 3,60) left wrist ulnar deviation (24,21±5,27), and radial deviation (18,27±2,88), left index finger hyperextension (34,48±7,52), left hand thumb finger flexion (40,00 ± 5,15). While there was no relation between static posture and pain, the intensity of pain increased with excessive angular values of neck flexion, shoulder abduction, and thumb flexion during cello playing performance (p<0,05).
Conclusions: In our study, we found higher risks for wrist, neck, thumb and index finger. Excessive shoulder abduction was also a cause of pain. Teachers can be informed about body biomechanics and the problematic areas. Student should learn how to use their body to inhibit pain.
